The contact owns a 2013 Porsche Cayenne. The contact stated while driving 30 MPH, there was an abnormal noise while shifting from first to second gear. The contact stated no warning light was illuminated. The contact took the vehicle to an unknown dealer, where it was diagnosed with needing the transmission to be replaced. The vehicle was not repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 102,300.
Grinding & clunking noise from drive train at low engine speeds. Took it to Porsche dealership in October, 2020. They did not fix the problem and I was told it is ok to drive. The noise is getting worse from initial whining to grinding & clunking noise. Online forums indicate that it is a common problem with Cayenne & macan models of Porsche. Porsche has acknowledged the issue on there website with warranty extension. When I call the Porsche customer support. They are not acknowledging the warranty extension. I think it is a major safety issue and need to be address by Porsche
Car has problem with acceleration. It hesitates and drives like the car is being held back. Acceleration is not smooth. Rough and shudder and herky jerky. It has a faulty transfer case which is well known and should be recalled.
Multiple transfer case failures. First at 50K miles (slipping between gears, followed by a severe jolt as the gear finally changed)'transfer case was replaced at my expense ($7000K later). Second failure occurred less than 6 months later at 55K miles (severe jolt when shifting from 3rd to 4th gear)'transfer case replaced under parts warranty. Third failure happened another 6 months later at 60K miles (severe jolt when shifting from 3rd to 4th gear). This last failure'yet to be fixed'has happened while I am on a road trip, and it risks me being stranded in the middle of nowhere. This issue is rampant among 958S. Porsche really needs to step up and fix this issue. It's reported rampantly on forums, with many owners reporting multiple successive failures like I have experienced.

The contact owns a 2013 Porsche Cayenne. While driving, a loud unknown noise was heard from underneath the vehicle. The vehicle was taken to an independent mechanic who diagnosed that the transfer case needed to be replaced. The vehicle was not repaired. The dealer and manufacturer were not made aware of the failure. The failure mileage was approximately 85,000.
Purchased a 2013 Cayenne Porsche gts with 67K miles on it. Noticed a kind of thumping sound when accelerating, usually appearing at 3K rpms. Vehicle shudders and almost feels like the transmission is slipping. Took the vehicle to a mechanic to diagnose the fault and they immediately knew what it was, engine transfer case failure. This is due to a design flaw allowing water into the transfer case that Porsche is aware of and yet to address. On some occasions Porsche will pay for the $5K repair but the part is still replaced with a transfer case with the same flaw. Transfer case failure can lead to a sudden lose of power and potentially cause death or serious injury if someone is traveling at highway speeds. Highly recommend addressing this with a recall for 2013 and 2014 Cayennes. I have experienced sudden lose of power due to transfer case failure, neatly resulting in a highway collision.
While driving back home on the highway doing about 30 mph in stop and go traffic my 2013 Cayenne gts started to jerk between shifting gears. I thought it was a bumpy road at least but then after the traffic was over and I was able to pick up some speed to up to around 40-45mph the car shut off in the middle of the highway not knowing what to do. My life literally flashed in my eyes I was so lucky to get out of it with no injuries after researching and visiting my mechanic I was told that it was a transfer case issue and it's a very common thing to happen on Cayennes with gasoline engine
Transmission transfer case issues immediately after acceleration between 3rd and 4th gear. Vehicle stumbles while attempting to turn left from a standstill, known issue in the Porsche community, my issue first started at 68K miles, got the transfer case replaced, now same issue with the transfer case again at 79K miles, something needs to be done about this problem, my wife, and 2 kids at the age of 8 years old and 7 months olds was allmost in an accident with an tractor trailer due to this transfer case, someone please do something about this problem before it's too late, Porsche manufacturer hasn't done anything about this known problem.
Failure of transfer case at 51,000 miles and again at 78,000 miles. Porsche acknowledges problem nationwide but will not cover repair. Vehicle shutters/stutters and does not shift into gears (4 to 5). This failure is described countless number of times on the internet in various forums. Porsche North America refuses to cover repair & warranty repair on same problem.
Vehicle in motion suddenly shutters and slows. Sometimes vehicle will fail to move from stationary. Dealer diagnosed transfere case problem. Internet is full of similar complaints. Porsche admits design flaw, but will not assist. This is a severe safety problem. Vehicle ha 60,000 mi on odometer.
Transfer case failing 43,000 miles. Toxic fumes entering cabin, vehicle jerks and and does not function. Wife was almost killed as vehicle failed to accelerate out of the way of a semi- truck. Gathering data now to begin legal proceeding. The NHTSA will also be named in the lawsuit as they are failing to properly protect consumers from dangerous vehicles.
Transfer case fails very often. It causes the vehicle to jerk and unstable during driving. Porsche hasn't addressed this issue even though it is a very common problem on Cayennes.
4 wheel drive transfer case slips when driving, ongoing factory problem, faulty design from factory offered to cover some, I feel since it is a manufacturing defect the should cover the entire cost
